“…3 shows the kinetics process of EDCs on pillared Mt. Equilibrium concentrations of EDCs appear to be achieved after 1 h of adsorption, which is consistent with the rapid equilibrium times observed in other studies (Joseph et al, 2011). According to Cooney (1999), the adsorption kinetics is initially fast because adsorption takes place predominantly onto the outer surface, followed by a slow adsorption step onto the inner surface of the adsorbent.…”

-SnO 2 pillared montmorillonite clay was prepared and examined as adsorbent in the adsorption of endocrine disruptors compounds (EDCs) and compared with its starting material. The pillared samples showed a considerable increase in EDCs adsorption capacity in comparison to the natural clay mineral. This effect can be related to the textural and structural changes produced during the pillaring process. Consequently, Tin pillared clays could be the new material to be used in studied environmental process. Kinetics studies indicated that the multicomponent adsorption equilibrium was reached within 1 h and followed pseudo-second-order kinetics. The Langmuir, Freundlich, Redlich-Peterson and Temkin models were used to evaluate the EDCs adsorption capacity by pillared clay. The Freundlich model was found to be suitable for all compounds in a multicomponent system.

“…Each year, more than 6 billion pounds of plastic products containing BPA are produced worldwide [1]. Concerns have been raised that this compound could interfere with human internal secretion and induce a series of health problems even at low concentrations [2]. In addition, BPA can reportedly reduce fertility and cause cancerous tumors [3].…”

Detailed characteristics of adsorption of bisphenol A by highly hydrophobic MCM-41 mesoporous molecular sieves

2016

A surfactant structure-directing agent was used to synthesize a hydrophobic mesoporous material (MCM-41-d) at room temperature. As-prepared materials were characterized through X-ray diffraction (XRD) analysis, Fouriertransform infrared (FT-IR) spectroscopy, N 2 adsorption-desorption isotherm analysis, and thermogravimetry (TG). The properties of the samples for adsorption of bisphenol A (BPA) from water were also investigated in detail. The results revealed that pH affected BPA adsorption. Equilibrium and kinetic data were consistent with the Langmuir adsorption and second-order kinetic model, respectively. The adsorption capacity of MCM-41-d was considerably higher than that of MCM-41-c because of its higher hydrophobicity and more abundant adsorption sites. The maximum adsorption capacity of MCM-41-d was as high as 416.7 mg/g, indicating that MCM-41-d can serve as an efficient adsorbent to remove BPA from water.

“…C-ENMs have been shown to adsorb PPCPs such as bisphenol A [366,368,371], doxycycline hydrochloride [367], TBBPA [269], triclosan [372], ciprofloxacin [373], oxytetracycline [367,374], carbamazepine [375], norfloxacin [376], ibruprofen [372], and natural and synthetic estradiols [366,371,377]. Removal of EDCs by carbon-based ENMs is strongly dependent on the physicochemical properties of target pollutants such as aromaticity [367], octanol-water partitioning (K ow ) [366,371], sorbate concentration, and presence of natural organic matter (NOM) [372,378].…”
